These are a powerpoint presentation on chemistry A level notes on entropy.
The notes have been well written to help students and teachers undertaking chemistry a levels in edexcel IB and cambridge based syllabuses.
What is Entropy
Comparing entropy values
Predicting entropy change
Predicting sign of entropy
Calculating entropy change of a reaction
Spontaneous and non-spontaneous reaction
Calculating the entropy change of the system
Calculating the entropy change of the surroundings
Calculating total entropy change
ROLE OF TEMPERATURE
Why water freeze at -5 but does not at -5
More Entropy changes
Dissolving substances in water
SOLUBILITY OF GROUP 2 SULPHATES AND HYDROXIDES
Lattice energy and born Haber cycles
lattice energy
construct Born–Haber cycles
enthalpy change of atomisation and electron aff inity
eff ect of ionic charge and ionic radius on the numerical magnitude of a lattice energy
■■ interpret and explain qualitatively the trend in the thermal stability of the nitrates and carbonates of Group 2 elements in terms of the charge density of the cation and the polarisability of the large anion.
apply Hess’s law to construct energy cycles to determine enthalpy changes of solution and enthalpy changes of hydration.
■■ interpret and explain qualitatively the variation in solubility of Group 2 sulfates in terms of the relative values of the enthalpy change of hydration and the corresponding lattice energy.
Biology schemes of work for Cambridge IGCSE for term 2. Made from 2020-2022 Biology 0610 syllabus. The schemes of work are written for every teacher teaching 0610 extended syllabus. For core syllabus, check on other resources.
The schemes of work are professionally designed to include the week, lesson, topic, subtopic to teach, objectives as per the syllabus, teaching activities for each lesson, Teaching aids for each lesson and the remarks session for the teacher to fill if covered successfully or not.
IGCSE schemes of work for physics tutors teaching/handling year 9 students. The schemes are in line with the current syllabus for lower secondary students aiming to help them achieve their full potential and preparing them for upper secondary.

YEAR 12 CHEMISTRY INTRODUCTION TO ORGANIC CHEMISTRY ALKENES POWERPOINT NOTES WITH END OF CHAPTER QUESTIONS AND ANSWERS.
NOTES ARE RELEVANT FOR BOTH CONCEPTS IN CAMBRIDGE AND EDEXCEL IAL LEVEL CHEMISTRY.
U NIT 1 IAL
This Powerpoint material is suitable for students and teachers sitting and teaching chemistry in A LEVELS for all syllabuses.
The following are areas covered in this document.
1 explain that catalysts can be homogeneous or heterogeneous
2 describe the mode of action of a heterogeneous catalyst to include adsorption of reactants, bond weakening
and desorption of products, for example:
(a) iron in the Haber process
(b) palladium, platinum and rhodium in the catalytic removal of oxides of nitrogen from the exhaust gases
of car engines
3 describe the mode of action of a homogeneous catalyst by being used in one step and reformed in a later
step, for example:
(a) atmospheric oxides of nitrogen in the oxidation of atmospheric sulfur dioxide
(b) Fe2+ or Fe3+ in the I–/S2O8 2– reaction
4 understand that knowledge of the rate equations for the hydrolysis of
halogenoalkanes can be used to provide evidence for SN1 and SN2 mechanisms for tertiary and primary halogenoalkane hydrolysis
5 be able to use calculations and graphical methods to find the activation energy for a reaction from experimental data
The Arrhenius equation will be given if needed.
6 understand the use of a solid (heterogeneous) catalyst for industrial reactions, inthe gas phase, in terms of providing a surface for the reaction
